Figure 5 is a fragmentary side elevation of the door latch with the outer cover plate removed.

Figure 6 is a side elevation of a slightly modified form of construction.

Figure 7 is a side elevation of another modified form of construction.

Heretofore the case plates of door latches have been mounted upon the inner sides of the doors, and the latching bolts of auchv latches have been retracted from the outside of the doors by rotatable spindles extending through the doors. With such constructions, the pillars of the doors were usually quite large in cross section to accommodate these spindles, which ordinarily were spaced several inches from the free edges of the doors. Thus, the vision of the occupants of the vehicle was limited. Furthermore, when the outside operating means extended through the door, the vertically movable glass panels usually provided in the doors had tobe relay tively narrow so that the movement thereof would not be interrupted by the operating means for the latching bolt. To overcome these objectionable features, I have provided a latch having a case plate that may kloe-attached to a .door pillar having a veryv small' cross section. Moreover. bothlthecase plate and theloutside operating means for the bolt preferably straddle the guide-way for the,

vertically; 'movable glass. panel, hence' the pc-r 2, 1925. Serial No. 6,433.

vision and a wider glass panel may be employed.

Referring now to the drawings in which like characters of reference designate corresponding parts throughout the several views', the numeral 1 designates a door, preferably of a vehicle body, having a pillar 2 provided at its inner-edge with a channel-shaped portion 3 which constitutes a run-way for a vertically movable glass panel L1.

In order that a suitable vlatch may be mounted and operated upon the pillar 2 without interfering with the vertical movement of the glass panel, I preferably provide a case plate 5 that is U-shape in cross section and that preferably straddles the channel-shaped guide-way 3. With this construction, the lock is preferably attached to the door by means of suitable vheaded elements 6 that engage brackets 7, 8, and 9 respectively carried by the inner and out/er sections 10 and 11 respectivelyof the case plate. As shown, the bracket 7 projects laterally from the outer section 11 of the case plate and is preferably attached to the transversely extending portion 12 of the -door pillar 2; the bracket 8 is preferably detachably secured to the inner section 10 of the case plate and is secured to the inner side panel of the door; and the bracket 9 is preferably formed integral with the section 10 of the case plate and is also secured to the inner side panel of the door.

Slidably mounted on the inner section 10 of the case plate isa bolt 13, preferably Vhaving a shank 14 and an enlarged head 15. 8

As shown, the head 15 is guided by a substantially U-shaped bracket 16 secured to the section 10 of the case plate and is adapted to engage a suitable keeper (not shown) upon the door jamb of the vehicle body, While the shank 14 preferably extends between spaced guide lugs 17 struck out from the section 10 ofthe case-plate and is provided at spaced points throughout its lengthwith a laterallyy extending lug 18 anda depending extension 19. To provide a compact construction, the shank14 is preferably flat so that it may move behind' a suitable cover plate 20 secured to the sectionlfO ofthe case plate, while a helical springf21ffanchored. upon .the section A10 .of

the case plate has an arm 22 engaging the inner end of the shank 14 and is adapted to normally hold the bolt in projected position.

For retracting the bolt against the tension of the spring 21, I preferably provide a suitable roll-back 23 that is adapted to be operated from the outside of the door, and' a pivoted lever 24 that is adapted to be operated from the inside of the door. As shown, the lever 24 is preferably pivoted at its lower end to the inner section 10 of the case plate, preferably below the bolt shank 14 and'extends upwardly beyond the upper edges of the case plate. Intermediate its ends, the lever 24 is preferabl provided with an off-set portion 25 that receives the bolt shank 14 and engages the lateral lug 18. To prevent the lever from rattling, a lug 26 is preferably struck out from the inner section 10 of the case plate and serves as a stop for the forward movement of the lever, while a suitable lcoil spring 27 is preferably terminally secured to the lever and case plate section 10 and normally holds the lever against the lug 26. The roll-back 23 is engageable with the depending extension 19 of the bolt shank and is provided with a hub 28 that is journaled in aligned openings in the case plate and cover plate.

In order that the bolt 13 may be retracted from outside the door without interfering with the movement of the glass panel in the guide-Way, the roll-back 23 is preferably provided at its forward edge with a lateral extension 29 that preferably extends across the transversely extending portion 30 of the case plate and is adapt/ed to be engaged by the lateral extension 31 of a roll-back 32 having a hub 33 journaled in aligned openings in a cover plate 34 and the outer section 11 of the case plate. Any suitable means, (not shown) may be engaged with the square opening 35 in the hub 33 for rocking the rollback 32 so that the lateral extension 31 thereof will raise the extension 29 of the roll-back 23 and cause the latter to retract the bolt. As shown, the cover plate 34 is provided at its top, bottom and rear edges with inturned yflanges 36 that seat against the outer section 11 of the case plate land that are preferably provided at spaced points with lugs that engage openings in the case plate section 11 for positioning the cover plate thereon. Thus, with this construction, the roll-back 23 may be actuated to retract the bolt without affecting the lever 24 and the latter may in ,turn be swung to the rear against the lug 18 without affecting the roll-back. The spring 21 will alwaysl exert a pressure through the lug on the bolt shank against the lever so that the latter will normally be in operative position to retract the bolt. Likewise the spring will exert a pressure through the depending extension 19 of the bolt shank against the roll-back 23. This action of the spring normally holds the lateral extension 29 in engagement with the extension 31 so that these parts will normally be in operative position to retract the bolt from the outside of the door. As shown in Figure 5 of the "drawings, the roll-back 32 is 'preferably provided with a depending lug 37 that is engageable with the lower section of the flange 36 of the cover 34 lo limit the downward swinging movement of the roll-back extension 31.

In order that the outside operating means may be rendered inoperative from the outside ofthe vehicle, I'preferably provide a dog 38 that is pivoted on the outer section 11 of the case plate and is adapted to swing behind a lug 39 on the roll back 32 to prevent the upward swinging movement of the extension 31. This dog 38 is normally held out of the path of the lug 39 against astruck out lug 40 on the case plate section 11, by means of a coil spring 41 anchored on the case plate and may be moved by a suitable means into operative clogging` position. As shown, the dog 38 is preferably actuatedby a suitable cam 42 rigidly secured to the rotatable cylinder 43 of an auxiliary lock 44 which is preferably anchored in a tubular housing 45 projecting laterally from the cover plate 34. This housing 45 may be secured in any suitablemanner to the cover plate 34 and any suitable means such as a screw 46 threadedly engaging the lateral attaching flange 7 on the case plate may be-employed for holding the .lock 44 within the housing.

In the modification illustrated in Figure 6, a dog 50 is adapted to be moved by the inside operating lever 24 into operative dogging position behind,a .shoulder 51 of the bolt shank 14-for preventing the bolt from being retracted from t e outside of the door. As shown, this dog is preferably pivoted on a pin 52 anchored preferably upon theinner section 10 of the case plate, and is normally held out of the path of thebolt shank by means of a suitable spring 53 secured to the case plate. With this construction, the dog 50 may be detachably held in operative do ging position by means of the lever 24. s shown, a suitable leaf spring 55 is anchored upon the inner section 10 of the case plate and is providedl intermediate its ends with an embossed rib 56 that is-engageable with a suitable depression 57 in the outer face of the lever 24 when the latter is in its forward position. This rib 56 normally serves as an abutment. for the forward edge of the lever when in inoperative or neutral posit-ion and therefore prevents any objectionable play or rattling thereof. When the dog 50 is in operative position behind the shoulder 51 and the lever 24 is held by the spring 55 in its forward position, the lever may be readily operated from the inside of the vehicle to release the dog 50 and retract the bolt. This may be accomplished by moving the lever to the rear 'zoA so that the projection 56 of the spring 55 becomes disengaged from the depression 57,-

whereupon the spring 5.3 will automatically move the dog 50 upwardly out of the path of the shoulder 51. The roll-back 23 may then be operated from the outside of the vehicle if desired for retracting the bolt.

In .Figure 7 I have shown another modiiiwith a suitable crank portion 64 that engagesv the lateral projection 18 of the bolt shank 14.

From the foregoing description it will be readily apparent that a latch of this type may be readily mounted upon a door pillar having a very small cross section, consequently the fvision of the occupants of the vehicle is materially increased. Moreover, the mechanism for retracting the bolt from the outside of the door straddles the guide-way for the glass panel, hence the vertical movement thereof is not interrupted and a wider panel may be employed. lt will also be apparent l that the outside operating means and inside operating means may be independently operated for retracting the bolt. Furthermore one of the attaching brackets for the latch also vcarries the screw 46 that retains the auxiliary iock 44 within the housing 45 on the outside cover plate 3a'.
